Is Kotlin the right default for new Android apps, or is Java still worth choosing?

Kotlin is the default Google recommends, and for new Android apps it is the right choice in nearly every scenario. The language reduces boilerplate, eliminates entire classes of null-pointer bugs through nullable types, and interoperates with Java code at 100 percent fidelity for any legacy libraries the project still depends on. Java still makes sense for legacy codebases that are too large to migrate in one pass, but new modules in those codebases are usually written in Kotlin and called from existing Java code without friction.

Should we use Jetpack Compose or the older XML view system for the UI?

Jetpack Compose for greenfield projects, no real debate at this point. Compose has reached production maturity, ships with the modern Material 3 component library, and pairs naturally with Kotlin coroutines and state-driven architecture. Compose lets you build, restyle, and animate UI in a fraction of the XML-based time. We still use the XML view system inside existing apps that have not migrated, and we mix Compose into XML hierarchies through ComposeView when a phased migration makes more sense than a full rewrite.

What's a realistic timeline for shipping a production Android app to the Play Store?

A focused single-feature MVP with eight to twelve screens, a backend integration, authentication, and analytics typically reaches the Play Store in 10 to 14 weeks. A full enterprise build with offline sync, push notifications, payments, and Wear OS companion runs 16 to 22 weeks. First-time Play Store review typically resolves in 1 to 3 days, but apps that handle payments, health data, location data in the background, or content for kids should plan an extra 1 to 2 weeks of policy review and possible revisions.

How do you handle the device and OS fragmentation that Android is known for?

Three things. We define a minimum supported API level early, usually covering 95 percent or more of devices in the target market, and we hold that line through development rather than letting it drift. We test on a curated device matrix that covers the actual phones and OS versions used by the customer base, not just the latest Pixel. We use Jetpack libraries that abstract version differences and shim newer APIs onto older devices wherever Google provides a backport. The result is an app that behaves consistently across the long tail of Android phones, not just the flagship.

Can a native Android app share business logic with iOS or web?

Yes, through Kotlin Multiplatform Mobile. KMM lets you write shared business logic, networking, and data layers in Kotlin and call them from native Android (Kotlin), native iOS (Swift), and web (Kotlin/JS) targets. The UI stays native per platform, which is the right place for native fidelity, while the parts that benefit most from sharing live in one codebase. We use KMM where the team genuinely needs to ship native iOS and native Android with shared logic, and we use full-native Android when the project is Android-first or Android-only.

What We Build

Android Capabilities

What we ship in native Android with Kotlin and Jetpack Compose, from phone and tablet to Wear OS and Android TV.

Kotlin + Jetpack Compose

Google's modern Android development stack combines Kotlin's concise syntax with Jetpack Compose's declarative UI, delivering faster development and a smaller bug surface.

MVVM and Clean Architecture

Production Android apps with ViewModel, LiveData, and Repository pattern provide an architecture that scales from 1 engineer to 20 without codebase degradation.

Room and Offline-First

Room database with offline-first architecture keeps apps working without connectivity and syncing reliably when back online.

Android Security Best Practices

Encrypted local storage with Android Keystore, certificate pinning, root detection, and ProGuard obfuscation provide a security architecture suited for banking and healthcare apps.

Google Play Distribution

End-to-end Play Store submission covering automated AAB builds, staged rollouts, in-app review prompts, and Play Console analytics integration.

Background Services and Workers

WorkManager for reliable background task execution handles push notifications, data sync, media processing, and scheduled jobs with battery-optimal scheduling.

Questions? We've Got Answers

Your Native Android Questions, Answered.

Direct answers on when native Android in Kotlin outperforms cross-platform frameworks, and when a shared codebase makes more sense.

Featured Answer

When should an app be built natively in Kotlin versus using a cross-platform framework?

Native Android in Kotlin tends to fit when the app needs deep platform integration like advanced ARCore work, when performance demands require fully native rendering, or when the team has strong Android-only expertise. Cross-platform frameworks fit when you need to ship iOS and Android with one team, when 80 to 90% code sharing produces meaningful speed-to-market gains, and when standard UI patterns suffice. The trade-off is engineering velocity against platform-specific capability. Most consumer apps choose cross-platform. Most performance-critical or hardware-tied apps choose native.
